Oftentimes I see comments that go along the lines of "+1, really good answer/question!", "I agree, we should do that this way", or "This helped a lot, thanks!". These comments are encouraging and rewarding to see, but (1) upvotes already provide support/approval from the community and (2) as stated multiple times, including in both in the FAQ and the About section, that Ask Ubuntu is for Q&A, not discussion. Additionally, I often see "@user, I updated my post." Should I flag these comments for the sake of keeping Ask Ubuntu cleaner and tidier, or is this not necessary?
